Nitrox Upgrade


Breathing Oxygen-enriched air (Nitrox) on your dives gives you the advantages over regular air of diving longer, and doing shorter surface intervals. Nitrox is the breathing gas of choice for dive travel, allowing more dives per day, letting you maximize your travel dollar. Nitrox is available at Lighthouse, and around the world at all major diving destinations. Nitrox can also be used to greatly lessen your susceptibility to decompression sickness (the bends). This upgrade includes an academic session, and diving Nitrox on 2 of your open water dives.



Do you want to extend your bottom time, lessen your surface interval, and maximize every dive? The NAUI Enriched Air Nitrox diver upgrade is combined with other NAUI training programs such as NAUI Scuba Diver or NAUI Advanced Diver.

During this course, you will learn how to choose the proper blend of Nitrox for your dive profile, determine maximum depth limits for your Nitrox mixture, analyze your breathing mixture, and plan and safely execute each dive. Your instructor will teach you about the physiology of oxygen and nitrogen; advantages, disadvantages, and risks of nitrox; oxygen toxicity; hazards and precautions of handling oxygen; the concept of Equivalent Air Depth; use of EANx with standard Air Dive Tables; common gas mixing procedures; and more.

Minimum age for participation is 10 years (Junior EANx certification) or 15 years (EANx certification). Divers must be in good physical condition to enroll in a NAUI Enriched Air Nitrox Diver course. Participants may be enrolled in a NAUI Scuba Diver Course or NAUI Advance Scuba Diver Course. To enroll,
